We would like to use Performer solely as a renderer on SGI platforms,
hiding Performer specific calls by supplying a wrapper around some
of the available calls, and hiding the Performer specific data
structures completly inside our C++ classes.
To be able to do this we have to be sure, that pfGeodes and pfGeoSets
once they have been created stay in Memory where they have been created.
We have to be sure that Performer does NOT shift them around once we
remember a pointer to one of the structures.
The question is at which stage of the performer tree generation (e.g. by
one of the loaders) can we be sure of that?
Does the rendering pipeline copy the data to different places or will
it always (if not deleted, of course) stay in the same place?
Any recommendations?
